The capacitive measuring principle is one of the most precise measurement methods for non-contact displacement measurement. The measurement principle requires a clean environment. The sensors measure against all electrically conductive materials. Capacitive measurement systems from Micro-Epsilon operate with a unique, active, low noise cable in combination with an active guard ring capacitor. A particularly high quality signal is achieved due to the double shielding of the field. The system has an almost perfect impermeable electrical shield, which ensures precise measurements.
Capacitive displacement sensors from Micro-Epsilon are differentiated by their measuring range, their design and by the technology used to manufacture them. The capacitive sensors are available in a cylindrical design (with integrated cable or socket) or as flat sensors (with integrated cable). For special applications measuring systems can be modified: e.g. modified designs, target coordination, mounting options, individual cable lengths, modified measuring ranges or sensors with integrated electronics.
